They can be seen from miles around and have been dubbed the Eiffel Towers of south London.

Even considered as a homing device for people to spot when travelling to Upper Norwood, the two transmitting towers are instantly recognisable.

The towers on Crystal Palace Parade, in Bromley, and Beulah Hill, Croydon, have more than 60 years’ worth of history, and are still working as well as they did when they were first installed all those years ago.

Bromley’s tower, located closest to the park, was the tallest structure in London until the construction of One Canada Square, at Canary Wharf in 1991.

It was constructed among the remains of the Crystal Palace, 20 years after the infamous fire in 1956, and the 219-meter tall tower was built by the BBC for transmitting services.

The BBC, according to local historian John Hickman, had wanted to have a follow-on transmitting server from Alexandra Palace – one that would cater for the South East.

Mr Hickman said it came at a time when owning and watching television was booming in the UK.

He said: “The BBC tower was the first to be erected [of the two] and is on the site of what was part of the Crystal Palace.

“It, as well as the other tower, was built to serve and transmit to all of the South East.”

He added: “Television had really taken over after the end of the second world war, particularly after the coronation of the Queen.

“If you ask most people what the first thing they saw on television, it would have been the coronation of the Queen.”
